An improvement of the Albritton nonlocal electron heat transport model is proposed for high-[ital Z] plasmas. The thermal decay of the temperature perturbation in a uniform plasma as calculated by this model is compared with that obtained by Fokker--Planck simulations. Complete agreement is found up to values [ital k][lambda][sub [ital e]][congruent]0.1, where [ital k] is the wave number of the perturbation and [lambda][sub [ital e]] is the thermal electron mean-free path.
